In this era when many people have neglected to learn what the Bible says and have pushed aside the truths of historic Christianity in society, too many people are unaware of how powerfully Christian ideas can change their lives and the world for the better. They need faithful Christians like you to communicate the faith’s most revolutionary ideas to them in fresh ways.

Here’s how you can reach others for Christ with seven uniquely Christian ideas that changed the world when they were first introduced and still have the same revolutionary power:

Help people understand the resurrection. Christianity is the only religion in the world’s history to make the startling claim that not all dead people stay dead. Historical evidence abounds of Jesus Christ’s bodily resurrection after His sacrificial death on the cross. Not only did Jesus Himself come back to life after death, but He promised that everyone who places their trust in Him will also be able to live again after they die, and to live forever with Him. This astonishing promise has great power to give people hope. Thanks to the resurrection, Christians never need to fear death – the most common fear among human beings – and can actually look forward to it as a blessing, because it will usher them into God’s presence and a wonderful life throughout eternity.

Help people understand that God walked the Earth. Jesus Christ is the only religious leader in history who claimed to be God incarnate. The fact that God visited Earth in the form of Jesus Christ shows just how much God really cares about human beings. God was willing to subject Himself to the limitations of a human life to show us His love in the most up close and personal way possible. God endured suffering to pay the penalty of sin for us, so we could be connected to Him in relationships. No other religion shows God’s love at work in such a powerful way. Jesus reconciled God and humans completely, empowering Christians to change every part of human society for the better because His Spirit is at work through them.

Help people understand that the cosmos had a beginning and was fine-tuned. Christianity affirms that God brought the universe into being from nothing, creating the cosmos at a definite point in time and designing it in fine-tuned ways to support life. Scientific research also affirms that idea. The latest cosmological findings support what the Bible says about the universe emerging at a set time (the “big bang”) out of nothing that existed previously, and also support the Bible’s revelation that the universe was designed specifically with human life in mind. This gives people hope, because they’re not at the mercy of arbitrary, impersonal forces but instead are made and cared for by God, who loves them and wants them to know Him personally. Moreover, people aren’t set adrift in a random universe to fend for themselves, but can experience real care from God, who works do what’s best for them.

Help people understand why Christian faith explains reality much better than atheism does. The world makes much more sense when people accept the existence of the God of the Bible than it does when they think that there’s no God. Historic Christianity offers the best explanation of the realities that people encounter in life. The existence of the God of the Bible provides a rationally plausible explanation for: the universe’s existence; the universe’s beginning; the complex order, design, and elegance evident in the universe; the universe’s susceptibility to rational investigation; the reality of abstract, nonphysical entities; the presence of conscious beings in the universe; the reality of objective moral values; the purpose and significance that human beings yearn for in their lives; people’s innate sense of the divine; the enigma of human nature (greatness and wretchedness intertwined); the extraordinary life, death, and resurrection of Jesus Christ; and the meaningful realities of life by means of a cumulative case for God’s existence. People can best understand reality through a Christian worldview that accounts for abstract, intangible entities and encourages people to use their God-given, conscious minds to discover reality.
